The WaSP Buzz’ article on a new mobile web browser test made mention of phones that can read QR Codes—one of several types of 2-D bar codes that you see on things like shipping labels. In this case, the idea is that you can point your phone’s camera at the QR code and it’ll decode it and send you to the appropriate URL.

My first thought was that this was just like the CueCat, which was a bar code scanner that you could plug into your computer’s USB port, then scan bar codes in magazines, or on cans of soda, or whatever, and it would tell your computer to bring up relevant information. It was marketed in the late 1990s, during the tech boom… and it was a total flop. No one wanted them. The company went under and had millions of the little scanners sitting around unsold.

But now there are multiple schemes in use for object hyperlinking. In addition to graphical codes, there are RFID tags, GPS coordinates, and short text codes that you can easily type into an SMS message or a web portal.

So why is this sort of thing working now, 10 years later? Is it a societal change? Was the CueCat ahead of its time?

I think there are two reasons:

  • CueCat was a single-purpose device. All the applications listed involve smartphones or other multi-purpose handheld devices. No one wanted a device that would only scan bar codes, but a phone/camera/browser/MP3 Player/bicycle that also scans bar codes? Sure, why not?
  • CueCat was tied to the desktop. Sure, you could plug it into a laptop computer, but you’d still have to take the object over to your computer to scan the bar code. Unless you’re a lousy typist, swiping the CueCat across your can of Coke isn’t that much easier than typing in www.coke.com. As a home user, you’re not likely to be scanning a dozen objects in a row (unless you’re cataloging all of your books for LibraryThing).

All the applications listed on that page are mobile. A tagging scheme does give you an advantage when you’re out walking down the street and see something interesting. It’s much easier to punch in a short number than to try to type a URL on most phones, easier still to point your camera at a graphic, and dead simple to pick up an RFID tag or pull in GPS coordinates.

Update 2024: It’s funny: in the early 2010s I remember jokes about how no one outside of a marketing department had ever scanned a QR code, but now they’re all over the place, both for linking objects (a sign on a fast food door to go to their online ordering service, a code on an instruction manual to open a site with jump to a site with any changes since printing) and for sending data between devices (communications apps, 2FA apps, starting a download on a mobile device using a QR code shown on a desktop display).

I appreciate the fact that Apple provides a single updater for all their Windows software. It’s nice to consolidate things a bit with the profusion of updaters for what seems like each and every application (sort of like how every mobile device seems to need its own charger). But it has its flaws. I’ve mentioned some broken UI design, but the most annoying thing is that it tries to install new software instead of just updating what you have.

At work, I have QuickTime and Safari for development purposes. I don’t have iTunes. I don’t need it. I don’t even have speakers hooked up to the computer. But every time a new version gets released, it shows up in the Apple Software Update list, and I have to tell it to ignore it until the next time they update iTunes.

Now that Safari for Windows is out of beta, it’s doing the same with Safari*. And people are complaining. People like John Lilly, CEO of Mozilla, who sees it as an anti-competitive measure that dilutes users’ trust in software updaters.

Personally, I think there is a problem, but I hardly expected it to turn into the firestorm it has, with Asa Dotzler, c|net, digg, Techmeme, [edit] and now Slashdot, [edit 2] Daring Fireball and Wired (it just keeps going!), and dozens hundreds of commenters entering the fray.

There’s a simple solution, and it’s one of those rare cases where Microsoft gets something right in their software that Apple gets wrong.

  1. Create a separate section for software that isn’t already installed, and label it clearly. It can be in the same list, as long as there’s a separation and a heading.
  2. Leave the new stuff unchecked by default.
  3. Added: If set to check automatically, don’t pop up a notice more than once for each piece of not-installed software.

That’s it. Done. Apple still gets to leverage their installer to make people aware of their other apps, but there’s no chance of someone accidentally installing Safari (or iTunes) by accident because they didn’t read the list too closely. Take a look at Microsoft Update and how they (currently) offer Silverlight. It’s in a list of optional software, and it’s not checked until you choose it.

That’s all this really comes down to: sensible defaults and proper labeling.

Update: Well, two out of three ain’t bad.

*I have to admit getting a kick out of the title, “Apple pushes Safari on Windows via iTunes updater,” because my problem is that they’re pushing iTunes on Windows via their Safari updater. It’s a matter of perspective.

Hoosgot advice on selecting a compact laser printer for occasional home use? I’m looking for something that can handle going for weeks of inactivity without requiring excessive maintenance. Black & white is okay, since I’d rather take photos to Costco anyway.

It seems like every time we use our current inkjet, either the ink has dried out or it’s clogged the nozzles, and no matter how many cleaning cycles we run, the output always seems to have broken lines. I’m thinking a laser printer might work better, but I have no idea how much maintenance is involved.

What I’m looking for:

  • Small.
  • Can be turned on after a month or two (or more) and actually work.
  • Black & white is fine.
  • A built-in network interface (Cat5 or wireless) would be nice.

So how often does toner need to be replaced? Is it strictly on how much gets printed, or does it “go bad” in some way (like ink drying out) over time? Does the printer need to be cleaned if it’s not used? Would I actually be worse off than before?

Thanks in advance!

This is a bit of an experiment. I’d seen something about Hoosgot a few months ago: basically it’s a way to pose a question to the Internet.

Another Geek Hierarchy. This one, instead of focusing on how geeks of all stripes rank themselves, portrays the way “mainstream society” ranks geeks. I appreciate that it includes sports geeks. I’ve never understood why it’s considered acceptable to paint yourself blue, wear cheese on your head and giant foam gloves for a sports team, but wearing a Star Trek uniform makes you an outcast.
